' scription of the invention, which will enable others skilled in the art towhich it appertains-to make and use the'same.

This invention relates to pressure tanks for vapor lighting systems and pertains more particularly toa tank having a division wall or partition for dividing it into two com-- partments; one for containing air under pressure, and the other a hydrocarbon.

An object of the invention is to provide a tank for the purposesdescribed, having two compartments,- in which the air-pressure in the air compartment will not be lost when in the act offilling the other compartmentwith the hydrocarbon.

Another object is to provide a pressure tank having aseparate compartment for air and a separate compartment for a hydrocarbon in which but few fittings or parts are necessary and in which, also, all the said fittingsor parts are mounted upon thet'op of said tank.

For certain uses of the tank, for instance when in connection with individual lamps at street corners and other out-of-door use it is often a requirement that the parts or fittings shouldall be mounted upon the top of the tank so as not tobe inthe way of or interfere with other structures entering into the structure of the lamp mechanism. This disposition of: theparts is also desirable since said parts can be readily reached and manipulated.-

l' n-the accompanyingdrawing which illustrates my' invention, Figure 1 is an elevation of'my improved pressure tank, in part section', and shown together with certain con-- nections. Fig. 2 is a detail, in vertical section, 0t parts shown in Fig. LandFig. 3 is a vertical transverse section of a part of the apparatus shown in Fig. 2 taken on lineman ofthat figure.

The tank is indicated as a whole by the letter A andit is provided with a partition B at any desired point to divide said-- tankinto two receivers Can'd D, the former for receiving air under pressure, the latter for receiving the hydrocarbon which supplies the lamp or lamps of the lighting system.

is a pipe secured at one end in the partition B and opening at its other end through the top of the tank to which itis secured in an air tight manner or so that there can be no escape of air around it from the compartment G,

Secured on the top of the tank in any suitable manner and communicating with the pipe E is a fitting F. This is preferably a casting provided with two lateral extensions G, H, each having a passage J, K respectively Connected to the extension H is a hollow wire or other tubular conduit L which leads to the lamps of the lighting system.

Secured to the extension H is a pipe Mconnected with a fitting N securedin a suitable manner to the top ofthe tank A and communicating with the receiver or compartment C through a passage 0. This fitting has a lateral extension P provided with a passage P with which the said pipe M communicates and it also has at the opposite side an extension Q having a passage R Both these passages communicate with the main passage 0, described, and the latter communicates through an upper extension S with a pressure gage '1. A valve U lies in the passage R- and seats at its end in the passage P and closes it from communication with the passage 0. Mounted upon the extension Q or casttherewith is a tubular part V which communicates with the passage R through apassage W, Fig. 3. Extend-ingfrom saidpart V is a tubular exten sion 2 whose passage 3' communicates with the said passage WV, and a valve 4: is adapted to seat in one of said passages so as to cut ofi communication between the two. Lying within the pipe E is a pipe 5 which is smaller than the bore of said pipe E and the bore of the said fitting F, and whose upper end ter-e minates in the latter between the passage J and the passage K and communicates only with the latter. A valve 6' is adapted-to seat in the passage K sothat communication between the said can 'be interrupted as desired, there being no communication Whatever at any time be tween the passage J and said pipe-5', nor between the latter and the pipeE,

'? indicates a pipe extending through the" pipe and the said passage fitting F.

My invention is particularly adapted for lighting systems where the flow of fluid is to be automatically interrupted and, though not shown, said mechanism has control of the valve 6 whereby the fluid may be stopped in its flow at a predetermined time;

In practice an air pump is connected with the extension 2 of the part V by which air under pressure can be stored in the receiver C. This is done by opening the valve 4.

The air will then be forced through the passage W of the extension of the part V, and the passages It and O of the parts Q, and N respectively. The air from the receiver G can-now be allowed to enter the receiver D enters said compartment.

plpon the lighting-fluid by opening the valve pipe M and the passage J of the extension G into the fitting F and pipe E and then The pressure now causes the fluid to arise within the pipe 5 and if the valve 6 is open it enters the passage K and passes to the conduit L and the lamp'system so long as said valve 6 is open.

'Since the air receiver is tightly closed to all escape of air except through the fitting N, pressure can be readily held therein. But it is observed that the air in order to reach the receiver D must follow the course above outlined and that the air would be exhausted at once upon the removal of the cap 8 from the fitting pipe 7 unless a bar to its escape were employed. That there may be no escape the valve U in the fitting N is employed so that when said pipe 7 is opened egress of air by the way of said fitting is impossible and the only air lost is that within the receiver D. At the same time the passage B, through which the said valve extends allows pump pressure to enter the receiver C from the part V.

My pressure tank is distinguished from those of which I am aware in that in having the two receptacles preferably comprised in one structure, there are but two connections passing through and extending between the said receptacles z. e. the pipe 7 for filling the hydrocarbon receptacle D, and the pipe E for the introduction of air into the latter. The pipe 5 for the discharge of the hydrocarbon is carried up through the'pipe E and thus no extra opening is made necessary in the wall of the tank for it nor in the divid- It passes through the extension P, the
